5.3 Turbo Thirdgen winter project

Truck manifolds would probably have worked if we had a rack and pinion set up.

Had to notch the K member for the oil pan. I went a bit too far forward but it makes pulling the engine/4l80 in and out alot easier with the longer notch. 1/8" plate was used to fill the notch in, and it looks thicker then what was there before.



Homemade 4l80 w/ TA crossmember, still working on the TA mount, its a bit hard to make a clamp to hold the bushing when you dont have a vice


Homemade Gen III valvespring compressor, first project with the plasma cutter, not the prettiest, but it worked like a charm.

Ran into an issue with the fuel rail and the truck coils
The Best V8 Stories One Small Block at Time

Got the 02 driverside manifold in, works nicely and clears everything.
Kinda at a stopping point until more comes in, I want to finish up the swap/turbo build for the most part before the body work starts.
as a side effect it works excellent in vettes and also and most any other swap with large engine bay .tee hee.
see sig vv

Thanks for the insight on the fuel line, I didnt want to bend it unless I had to, I have a round coil as one of the square ones got broken, so I might see if I cant fit it by the fuel feed to clear with out bending. If it comes down to it, aftermarket rails will be ordered, or these will have -6 an fittings welded on the end and the cross over removed/welded up.

I've got a couple extra fuel rails lying around if you need some, just let me know.
Having been exactly in your shoes (sans turbo
) i feel your fitment pains.It was like deja-vu reading through here, i tried the same mounts, i had teh auto, i used a 5.3....everything.
As for the mounts, IMO, your toying with something i really didnt want to. Those mounts move the motor about 1.2" further forward then the original position. I measured it all out, i mounted my motor in like that and decided i didnt want to shift the weight forward, as i wanted the weight further back. The mounts also move the motor foward enough that you will need a custom driveshaft. Whether you like it or not, you wont have enough of your yolk going into the trans. Theres a thread on TGO about using these mounts, as i went throught it all in january of last year.
My soloution was i bought f-body mounts that bolt to the motor, made myself some U-straps, placed the motor int the car so that it was exactly where the original motor was (the trans mounting flange) and then welded it in. Ill dig up some pictures for you, but i seriously advise you do this, or get hawks mounts, it will save you the hassle of a driveshaft, and im thinking you also want the motor closer to the rear then front.
As for the manifolds, yeah, the truck ones suck, they hit both sides, i cut both flanges off, and clocked them a different way in an attempt to get fitment but no dice. Ended up fabricating myself some custom headers.
As for your fuel rails, yes, you can bend them over a slight bit to make them fit, its tight, and the quick disconnect plug is kinda bulky and makes it hard.
Also note, that truck coils dont allow the use of Vette FRC's.
Trying to think of everything else i went through in my swap, i did use an electronic TB, truck TAC and then i took a truck pedal, and cut it up and welded it to make it fit.
Ill note that my 5.3L has now been shredded and an LS1/6 put in its place.
On a further note, want to sell me one of those (or both) turbo's?

Feel free to PM me if you have any questions
